Chem 12 question? Can two solid substances from the same phase (s) be heterogeneous reactions? The reason is that in heterogenous reactants, there is a surface area. When you place the two solids, they have a surface area in which reaction is slowly taking place.

    My teacher told me it is homogeneous reaction because of the same phases, but I found somewhere that it can be heterogeneous reaction. What do you think @Shalante ?

    There can be two answers, but one is more preferable.

    I would say its homogeneous since the 2 reactants have the same phase. 2 solids on top of each other? Isnt that still 2 solids?

    Right, but what about the blue surface area that they have in common. That is the feature of heterogeneous reaction.

    What is it called?

    Are you asking my own opinion?

    If they have something in common, it would be homogeneous. Homo-same Hetero-different Homogeneous is uniform while heterogeneous varies.

    That is true, so the same phases would be the similarity. Lets go with homogeneous reation. However, what that teacher told me in the video was confusing and made me skeptical.
